Plant Buffers May Limit Spread Of Antibiotics In Animal Waste

Research by scientists at the University of Missouri Center for Agroforestry suggests that buffer strips of grasses and other plants can trap and break down veterinary antibiotics in manure fertilizers. Buffer strips have already demonstrated that they can be effective in protecting water quality, controlling erosion and supporting wildlife around crop fields. "That's the beauty of it, " said Keith Goyne, assistant professor of environmental soil chemistry in the MU School of Natural Resources. "Vegetative buffers already are a recommended practice for reducing sediment, nutrients and herbicides in surface runoff. Our research is showing another benefit.

What Is Oral Thrush In Babies? What Causes Oral Thrush In Babies?

Oral thrush is a common fungal infection in the mouth of healthy babies under two years old. It is also called oral candidiasis. The condition is most common in babies around four weeks old. It is rare in the first week of life. Older babies can get it too, but this is less common. In some cases, babies can have repeated infections. Oral infections by the fungus Candida albicans usually appear as thick white or cream-colored deposits on mucosal membranes. Oral thrush in babies is not usually linked with other illnesses or conditions. Symptoms include an oral rash in the infant's mouth, a diaper rash that does not heal with conventional diaper rash treatments and ointments.

Protecting Patients: Study Shows That Johns Hopkins Flu Vaccination Rates Are Twice The National Average

A campaign that makes seasonal flu vaccinations for hospital staff free, convenient, ubiquitous and hard to ignore succeeds fairly well in moving care providers closer to a state of "herd" immunity and protecting patients from possible infection transmitted by health care workers, according to results of a survey at The Johns Hopkins Hospital. In a report published in the Feb. 1 edition of the journal Infection Control and Hospital Epidemiology, researchers say the rate of seasonal flu vaccination for the 2008-2009 season among health care workers at the Johns Hopkins East Baltimore medical campus, including The Johns Hopkins Hospital, was double the national average.

Scientists Prove Hypothesis On The Mystery Of Dengue Virus Infection

A leading immunology research institute has validated the long-held and controversial hypothesis that antibodies - usually the "good guys" in the body's fight against viruses - instead contribute to severe dengue virus-induced disease, the La Jolla Institute for Allergy & Immunology announced today. The finding has major implications for the development of a first-ever vaccine against dengue virus, a growing public health threat which annually infects 50 to 100 million people worldwide, causing a half million cases of the severest form. "Our lab has proven the decades old hypothesis that subneutralizing levels of dengue virus antibodies exacerbate the disease, " said La Jolla Institute scientist Sujan Shresta, Ph.

Grasping Bacterial 'Friending' Paves The Way To Disrupt Biofilm Creation

Finding a biological mechanism much like an online social network, scientists have identified the bacterial protein VpsT as the master regulator in Vibrio, the cause of cholera and other enteric diseases. This discovery, now published in the journal Science, provides a major tool to combat enteric disease. For decades, it has been observed that bacteria engage in biofilm formation in nature and the lab. Like the online social network Facebook, free-swimming bacteria ditch the solitary lifestyle to form a biofilm community, but only after they've signaled their intention to do so to others. The protein VpsT receives the invitation and accepts it by starting a cellular program facilitating the process.
